A Developmental Study on English Proficiency Test via the Internet

1.本研究的背景：2004年，该研究小组开发了一个实验性的基于计算机的英语水平测试，通过互联网使用的测试引擎，已在一个私人研究机构开发。然而，测试有一些障碍。(1)研究小组每年都要支付发动机的租赁费，即使小组成员将其用于学术目的。(2)无法将某些测试项添加到测试的测试项池中。为了扩大测试的测试项目池，测试项目池中的所有测试数据都必须替换为所有新的测试数据，其中包括新测试项目和池中的当前测试项目.本研究的结果（1）用本团队成员菊池博士开发的新试验发动机替换试验发动机。更换后，18名学生参加了笔试和机考。两项试验的供试品均从同一供试品池中取出。相关系数为0.90。(2)测试系统的修改：修改了系统，以便在不替换所有数据的情况下将一些新的测试项目添加到池中。

1. Background of this research : In 2004, this research group developed an experimental computer based English proficiency test via the Internet using a test engine which had been developed in a private research institution. However, the test had some snags.(1) The research group had to pay the rental fee for the engine every year even when the member of the team uses it for academic purposes.(2) It is impossible to add some test items into the test item pool of the test. In order to enlarge the test item pool of the test, all the test data in the test item pool had to be replaced with all the new test data which include new test items and current test items in the pool as well.2. The results of this study(1) The replacement of the test engine with a new test engine which is developed by a member of this team, Dr. Kikuchi. After the replacement, eighteen students took the both tests of paper-based tests and computer-based tests. The test items of the both tests were taken out from the same test items pool. The correlation coefficient turned out 0.90.(2) The modification of the test system: The system was modified so that some new test items could be added into the pool without replacing all the data.
